9 Claims.

This invention: relates to poster panels and more particularly to poster panels having a supporting structure and a display panel which may be moved between a raised display position and a lowered service position.

The principal object of this invention is to provide improved means for guiding the display panel as it is movedbetween the raised display position and the lowered service position. In this respect, guide tracks and guide rollers are utilized so that the display panel may be moved and guided with the least amount of friction and a guided counterweight is also. utilized to balance the weight of the display panel- With this arrangement one man may readily move the distions. I

A further object of this invention is to provide the guide tracks with inclinded portions which cooperate with the guide rollers to move the display panel against theborder frame of the supporting structure in display position and to move the display panel forward of the border frame when it is lowered to the service position. In this way the display panel is rigidly supported in display position but may be readily lowered tosenvice position. I

Further objects of the invention reside in the details of construction of the guide track and guide roller mechanisms.

Other objects and advantages will become apparent to those skilled in the art upon reference to the accompanying specification, claims and drawing in which:

Fig.1 is a frontelevational view of a poster play panel between its display and service posipanel forming this invention;

to service position; and

Fig. '7 is an enlarged sectional view taken substantially along the line 7-7 of Fig. 3.

The poster panel isgenerally designated at II] and it includes a supporting structure comprising horizontalsupporting braces II, I2 and I3 adapted to be fastened to any desired mounting-structure, not shown. A border frame I4, preferably made of sheet metal, is secured to the 2 horizontal braces II, I2 and I3. .A base member I4 also preferably made of sheet metal'is suit ably secured to the border frame I4. A display panel I5 is supported by the supporting structure and is adapted to be moved to a display position as shown in Figs. 1 and 3, and to be moved to a lowered service position as shown in dotted lines in Fig. 3.

In order to guide the display panel I5 for' movement between the raised display position and the lowered service position, the supporting structure includes a pair of vertically arranged guide tracks I5 secured to the horizontal braces I I and I2, and a pair of vertically arranged guide tracks Il secured to the back of the display panel I5. A counterbalance weight I8 is utilized for balancing the weight of the display panel I5.

In order to reinforce and make more rigid the border frame I4, it is providedwith flanges 20 around the periphery thereof. -Adjacent the opening in the border frame I4 it is provided with abutting surfaces 2I for receiving the. display panel I5 in abutting relation. A guard 22 is formed on the upper portion of the border frame to prevent moisture from entering between the border frame I4 and the display panel I5. The upper abutting surface 2I may be suit-.

ably secured to the border frame under the guard 22.

The display panel I5 is preferably a fabricated sheet metal panel having internal braces 24 and external braces 25 and 26.

Mounted on the upper horizontal brace II and interposed between the brace II and the border frame I4 are a pair of sheave housings 28, each rotatably carrying a sheave 29. One end of each of a pair of cables 30 is attached to the brace 26 of the display panel I5 and the cables extend over the sheaves 29 and are secured to the counterweight I 8. The counterweight I8 is provided with a pair of eyes 3| which accommodate a pair of cables 32 secured between the horizontal braces I I and I2. The cables 32 may be maintained taut by turnbuckles 33. The cables 32 act to guide the movement of the counterweight I8 which, in turn is connected through the cables 30 to the display panel I5. As the display panel I5 is moved upwardly and downwardly, the counterweight IB moves downwardly and upwardly for the purpose of counter-balancing the weight of the display panel I5. Utilizing the cable guides 32 and the sheave assemblies 29, as illustrated, makes possible counterbalancing of the weight of the display panel I5 with the least amount of friction. I 1

The guide tracks I6 are each of double channel form, as illustrated in Fig. 7. The guide tracks I6 are inclined at their upper ends, as shown at 36, and the upper ends of the guide tracks it are secured to the horizontal brace II by straps 31. The lower ends of the guide tracks I5 are secured by straps 38 to the horizontal brace I2.

A compound guide roller 40 is located within the double channel guide track I6 for rolling operation therein and is connected by a bracket Al to the external brace 25 of the display panel I5. Therefore, as the display panel I5 is raised or lowered, the upper portion thereof is guided by the roller 40 operating in the double channel track guide It. As the display panel is moved upwardly and downwardly and the roller 40 is 1';

operatin in the inclined portion 36 of the track guide I6, the upper portion of the display panel I5 is moved toward and away from the border frame I4.

The track guides I'l, carried by the rear of the display panel I5, are provided with inclined surfaces or cam surfaces 43 adjacent the lower ends thereof. Rollers 44 roll in the track guides II and are carried by arms 45 pivoted at 41 to brackets 48 secured to the horizontal brace I2.

The display panel I5 may be provided with a suitable latch and handle 48 for latchingthe display panel I5 in the display position, as shown in Fig. 3.'

When the display panel I5 is in the upper display position, as illustrated in Figs. 3 and 5, the rollers '46 are in the upper portions of the inclined portions 36 of the guide tracks I6 and the pivoted arms 45 carrying the guide rollers 44 are in the retracted position. As a result the display panel I5 is abutting the surfaces 2| of the border frame I4 and the display panel I5 may be held in this position by the latch member 48. The display panel I5 is, therefore, rigidly secured to the supporting structure.

When it is desired to lower the display panel I5 from the display position to the service position, the latch member 48 is operated and the lower end of the display panel I5 swung forwardly. This permits the pivoted arms 45 to swing downwardly by their own weight to the position shown in Fig. 6. As the display panel I5 is then moved downwardly, the extended arm 45 holds the lower portion of the display panel I5 forwardly of the border frame I4. As the display panel I5 is lowered, the inclined portions or cam surfaces 43 insure that the pivoted arms 45 move to their extended positions, shown in Fig. 6. As the display panel I5 is lowered, the

inclined portion 36 of the track guides I6 operate in conjunction with the guide rollers 49 to move the upper portion of the display panel I5 forwardly from the border frame I4. As the rollers 40 enter the vertical part of the guide tracks I6, forward motion of the display panel I 5 is stopped and the'display panel I5 thereafter moves vertically downwardly to the service position, as shown in dotted lines in Fig. 3.

When the display panel I5 is moved upwardly from the service position, as shown in dotted 44 enter the inclined portions 36 of the guide tracks I6 to move the upper portion of the display panel i5 rearwardly toward the border frame I4 and at this time the inclined surfaces or cam surfaces 43 engage the rollers 44 to swing the arms 45 upwardlytoward the position'shown in Fig. 5 whereby the lower portion of the display panel I5 also moves rearwardly toward the border frame I4. When the display panel I5 reaches the display position it abuts the surfaces 2| of the border frame I4 and may be latched in place by the latch member 48.

The guide rollers and guide tracks of this invention, therefore, provide a ready means for guiding the movement of the display panel with respect to the border frame with the least amount of friction.

While for purposes of this disclosure one form of this invention has been illustrated, other forms thereof may become apparent to'those skilled in the art and, therefore, this invention is to be limited only by the scope of the appended claims.
